What is considered dense packing?

[Squidward]

I have seen some different thoughts on this, my last talk was with Dr. Nadimi where she said her dense packing was 40/50 per sq cm, now, I see some of these overseas Dr.'s going and achieving successful much higher most of the time atleast 60 cm per sq cm, thoughts?

It all depends on your hair characteristics as well. Fine hair needs a higher per sq cm than course and thick hair.

There's a point where aesthetically it can be diminishing returns on adding more hair per cm, but it's subjective to each case and can't be ruled out too generally since some people need higher cm to achieve what others can with lower cm.

For example, I have very fine hair and almost 7k grafts in the frontal third, I don't know what that equates to per sq cm, but it's definitely higher than the very general 3k for the frontal third that you often see.
